Definitions
- FIG. 1 is a schematic configuration diagram of a hydraulic control apparatus using a hydraulic actuator according to the present invention.
- FIG. 7 is a schematic view illustrating a hydraulic actuator and a connection portion thereof according to a second embodiment in the hydraulic control apparatus according to the present invention.
- Figure 11 is a schematic view showing a hydraulic control apparatus using a hydraulic actuator according to a second embodiment of the present invention.
- the pressure reducing valve 120 is connected to the oil supply line SL and the oil discharge line DR, and the pilot valve 130 is connected to the oil supply line SL and the oil discharge line DR.
- the pilot valve 130 does not include the function of the check valve as a leak may occur when parallel with the check valve, the life is extended as it is implemented by only the pilot valve.
- the accumulator 140 supplements oil to the hydraulic actuator 110 so as not to lower the pressure in the actuator below atmospheric pressure to prevent bubbles from being generated, and to prevent overpressure and block pressure, the relief valve 150a and the block valve (BV) is connected and can be installed in dual to facilitate maintenance during operation.
